RADIATOR-SHUTTER.

Specification at Letters Patent.

Apnlicatlon led February 1'?, 1917. Serial No. 149,231.

Buffalo, in the county of Erie and State ofi New York, have invented new and useful Im )rovemcnts in Radiator- Shutters. of which the following is a specification.

This invention relates more particularly to that class of radiators which are used for cooling 'by air the water which is circulated around the heated parts of an explosion engine in automobiles and the li-ke for preventing the working parts of the engine from heconiin unduly heated. ln the Sunimer time the ffiill cooling;r area of such radins tors is usually required to obtain the maxiinum efficiency of the saine hut in the winter time it is desirable to cut down the cooling area thereof in order to wmpensate for the natural cooling efl'eet of the air which is of lower temperature at this time and there-hy adapt the eiiiciency of the radiator to the. changes in temperature. lt has 'heen heretofore proposed to accomplish this purpose h v covering the front side of the radiator more or less and onli7 expose so much of the. sainey to the air current as may he required to obtain the desired amount ot' coolingeil'ect on the circulating water. Such devices. as heretofore constructed have. however. heen ohjectionahle for the reason that thair were. unsightly h v reason of their loand also lrv reason of the fact that the cooling cli'ect of the all"4 was not distributed uniformly over the radiator throughouttlie entire height thereof and therefore calused non-uniform `eaI ninsion of the radiator.

t is the purpose ot' this invention to provide means for controlling the cooling effect of the air on the water passing through the detracting from the appearance vof tlie.radiator and also to accomplish this purpose in such manner that the cooling effect is distributed throughout the height of the radiator and uniform expansion of the saine is sgeiired.

In the accompanying drawings:

Figure 1 is a front elevation, partlxir in Section. of one form of automobile radiator equipped with an air controlling device einheader and hodying my invention. Fig. 2 is a horizontal section of the same, taken on line 2-2, Fig. 1. Fig. 3 is a side elevation. partly in section. ot' the radiator equipped with my improvements. Fig. 4- is a iragmentariY vertical longitudinal section ot' the radiator showing the shutters which control thc air supply in an open position. Fig. 5 is a fragmentary vertical` transverse section. on an enlarged scale. of partsl shown in Fig. l.

Similar characters ot' reference indicate ern-responding parts throughoutthe several i'icws.

Although my imln'oveinents are applicahle to radiators which muv vary somewhat in details of construction that. for example.

which is shown in the drawings for use in connection with my improvements comprises an upper water inlet hox or header l which receives the heated water from the explosion engine. a lower water hox or header 2 from which the cool water is returned to the engine which is to he cooled. and a plurality of radiating sections 8 which are arranged in a longitudinal row one hehind another in the direi-tion ot' the length of the radiator and each section comprising a plurality ot' upright water passages i which are connected at their upper and lower ends with the in' terior ol' the upper and lower water boxes and a plurality ot' horizontal air passages 5 extending lengthwise through the same. l`he water passes from the upper header downwardly through the water passages in the several radiating sections into the lower during such passage the saine is cooled or reduced in temperature by the stream of air passino rearwardly through the air passages am in contact with the walls ol' the water passages.` The several radiating sections or' the radiator are also separated from each other by intervening air distributing spares f which permit the air to spread het ween the adjacent radiating sections and thus insure a more uniform distrihntion ot' the cooling effect of the air on the water as it passes through the upright water conduits. ln the drawings three of such radiating sections are shown in connection with the upperand lower water boxes Jout it is to be understood that this number Aa plurality of horizontal liti may be varied to obtain the required cooling effect which may he necessary for the engine with which the same is associated.

My improvements are designed to permit of euttingolf part of' the cooling or radiating surface of the radiator in rear of the fore most radiating section and for this purpose the controlling means are arranged in one o the air distributing spaces arranged between two adjacent radiatingsections. As shown in the drawingggs` these controlling means are arranged in the distributing space 'between the foremost radiating section and the second radiating;r section but it is to be understood that these controlling means may be otherwise arranged at some convenient point between the front and rear sides of the radiator'. The particular embodiment of -iny improvements which are shown in the (,lrawings aizeonstrueted as follows:

7 represents a plurality of horizontal shutters, louvers or slats which are arranged in a vertical row in the first air distributing: space between the first and. second radiatingy sections. Each shutter extends partieally the entire width of the radiator and pre e erably constructed of sheet metal. These shutters are so mounted that they van be turned into a horizontal inoperative position in which they do not obstruct the lree passage of the air through the' radiator from the front to the rear side of the same, as shown in Fig. Kl, or the same may be turned into an upright position so that they obstruct the passage ol' the air through that part of the radiator in rear of the shutters. In the preferred form of the .shutters they are made of such width that when turned into their closed, upright, or operative position earl! shutter laps with one edge over the oder oi' the zixljsn'vnt shutter so as to more eiierllially shut oil the passage of the air through the radiatorsi-rtions in rear of the shuttewA As shown in the drawings, this is armmpislu-d by providing; the lower edge of raf-li shutter with :in otiset portion 8 whirl! in the closed or rertiral position of the shutters overhangs or overlaps the upper rdno of tho shutter next below the same, as shown in Fig. -l. i

Various` means may be provided for pivotally supporting tin shutters` that show n 1n the drawings being suitable. and comprising roel( shafts or spindles il' which are arranged transversely in a rvrtiral row between the first and second radiating` motion and each shaft being ooniwelrd with one ol' the shutters between its upper and lower lontr'itiulimil edgfes ,and journah-d adjacent to itsl opposite ends. in Marinos l() 'formed in upright supper-trug bars or plates 1l which are secured to oppo sito ends ol the :nl iarrnt radiator sections. finit-abill nuaus lor ronnefzting' nach o these shafts with its rispet-tire shutter consists in stamping attaching eyes or loops 12 from the body of the shutter and securi the respective shaft in these loops by sol( ering or any other approved manner.

The several shutters are preferably o erated in unison so that they open and c ose simultanermsly and for this purpose the correspondinir ends of the several rock shafts are roviiled with crank arms 13 each of wliic is provided at its outer end with a wrist 14 which. engages pivotally with an opening 15 in an upri ht shifting bar or rod 1.5. Upon moving t is shifting bar vertically in one direction the several shutters are turned into their open position while upon moving this bar in the opposite direction the several shutters are simultaneously moved int'o an open iosition. By shifting the shutters so that t ey occupy a position between their fully opened and their fully 85 closed position, it is possible to regulate the amount ot' air which is permitted to ass through the radiating sections in rear ot the shutters. This adjustment of the shutters is preferably el'eeted from some convenient 90 place, such for instance as the drivers compartment, by employing a shifting mechanism accessible to the operator. Although this shifting mechanism may be varied that for example which is shown in the drawings ooniprises an elbow lever 1G pivoted on the lower water box and having its lower front arm pivotally connected with the lower end of the shifting bar while its u per rear arm is connected with a shipper rot'17 extending 100 rearwardly to the operators compartment.

Owing to the arrangement et the shutters between the radiator sections the same are not visible from the front of the radiator and therefore do not detract from the appealance of the same. l` `urthermore it permits the cooling vater to distribute itself over the entire area oi the foremost radiating'section and thereby causes a uniform action on the same which would not be pos- 11( sible if only a part of this foremost radiator section were exposed to the air. This arrangement of the shutters also permits of either fully cutting,r oif those radiating sections in rear of the same or employing their I .5 coolingr efficiency to a greater or lesser-,extent as may be desirable.

Furthermore, if the front-side of the radlator should be. injured from any cause the air controlling,` mechanism will be unaffected but remain in an operative conditions() as to permit of adjusting the cooling efficiency of the radiator to suit the reqmrements of tho engine.

This air controlling mechanism is very simple in construction, the same is not liable to get outof order and it is possible to apply the same to many forms of radiators now on the market without requiring any alteration in the structure of the salue.

I claim as my invention:
